Equitix Welcomes HarbourVest Investment in Calisen Smart Meters via Secondary Transaction

Equitix, Europe’s leading small to mid-market infrastructure investor, is pleased to announce its partnership with HarbourVest Partners, a global private markets investment firm, in Calisen, a UK smart meter platform.

HarbourVest’s investment in Calisen was completed via a secondary transaction and will help accelerate the deployment of smart metering technology across the UK, supporting the energy transition, enhancing network efficiency, and enabling households to better manage energy consumption.

The commitment strengthens Equitix’s ability to support high quality UK infrastructure platforms that deliver resilient, stable, and inflation-linked returns, while providing HarbourVest with exposure to a mission-critical energy asset generating long-dated, with attractive cash yield.

The Calisen platform – one of the UK’s largest smart meter businesses – continues to play a central role in supporting the national smart meter rollout, offering secure, digitally enabled infrastructure essential to modernising the UK energy system

Paul Winters, Chief Operating Officer at Equitix, said: “We are delighted to strengthen our long-term partnership with HarbourVest. Their commitment reflects a strong confidence in our investment strategy and in the critical role smart infrastructure plays in enabling a low carbon future.”
